Auto Power Retract Mirrors Do Not Operate

MIRROR (EXT): POWER MIRROR CONTROL SYSTEM: AUTO Power Retract Mirrors do not operate
- AUTO Power Retract Mirrors do not operate

DESCRIPTION

When the mirror AUTO retract switch of the multiplex network master switch assembly is on, the multiplex network master switch sends the mirror AUTO retract switch signal to the main body ECU (multiplex network body ECU) via LIN communication. When the doors are locked or unlocked while the engine switch is off, the main body ECU (multiplex network body ECU) sends the mirror retract/return signal to each outer mirror control ECU assembly via CAN communication. On receiving the mirror retract/return signal, each outer mirror control ECU assembly operates the power mirror retract motor of the outer rear view mirror assembly to retract or return the outer rear view mirror assembly.
